Patented fune tot Mitts To all V710/uit muy Concern.: p

lle it known that l. Curiosos il. hintern,

a. citizen of the United States, and resident.

of Detroit, `Wayne county, State oit l'riiehi gan, have invented rertain new und use el lnin'o'veinents in ilydroeareen-hintere oit which the following is n specitieation.

This invention relates to l'iydrocar'oon motors :und particularlyv to the controlv'niecha- K nism therefor.

` vide a hydrocarbon motor having a governor and a toggle connection between the gow ernor andthe throttle valve, with a toggle mechanism for operating the irst toggle.

Another object of the invention is to provide a hydrocarbon motor with a double toggle mechanism for operating the throttle valve. I

@ther objects of the invention will appear from the following description taken in conneotion with the drawings which torni 4a part of this specification, and in which Figure 1 is aside ele ation of a hydrocarbon motor withY someparts out n.way; and Fig. 2 is e view similar to Fig. i with the throttle control mechanism in a. different nosition.

Referring tothe drawings, l() represents the motor base or crunk cose upon which are mounted the cylinder castings lil.` 'The intake heuderis shown :it i2 and the intake pine at 13. A throttle valve 14; is suitably arranged in the intake pipe to control vthe passage of ges' to. the motor. Shown as mounted upon the intake pipe 13 is e governor 15 which is of the diaphragm type. The flexible diaphragm isshown at lo" und it will be understood that the Water pressure acting upon one side oi the disphrsgm in opposition to atmospheric pressure on the other, tends to move the diaphragm to the right or to the left as the pressure rises und tells. The water pressure is reguluted entirely by the speed of the motor, ss the Water passing through the governor is delivered by a pump geared directly to the motor.

At the rear end of the motor bese is mounted a valve 17 which is suitably heldin closed position by means oi' a spring 18. rihis valve controls the motor oiling system, being arranged between the suppl oipes 17 unil 1T, the former receiving oi rom the motor driven pump 1? and the latter deliveringn it to the cylinder Walls through brunch pipes l.- 'ihus the valve 17 regulates the supply of oil to the nioi'or.

lieycd to the throttle valve 1li is e. late or .firm 19, which arm lforms one oi" the links ot a toggle mechanism connecting the throttle with* the governor 15. The other linlr of this mechanism is shown at Q0. .lin operating rod 2l is also connected to the arm or plate lil for o'ieruting the throttle in offposition to the tf rovernor, as will he clear y seen upon reference to the drawings.

placed under the control of the o )erntor either through a handcontrolled mecV :mism connected to' the rod through springs 22 and :i lever QS, or hy a :toot control device in the 2Q are arranged hetweensliding collars 25 on the rod Qi and n` stationery abutment 26 rod 2l. n yielding connection between the hand controlled lever 23 und the' rod 2l. The rear end of the operating rod 21 is connected to the rear end of the motor, and another `arm 30 of the rock shaft 29' is pivotally connected to :i link 31 Which-in turn is connected to a pivotcd lever 32 thus forming a toggle mechanism actuated hy the acceleretor pedal 2li. lhe rock shnit 29 is also pro vided with e third arm 33 which travelsin the. nath of the shank 34- ot' the oil veli/e rock shaft 29 is rocked forwardly. 1

lt will be understood that because of the lattv that the motor is usually running slowly,7 when the rthrottle valve is closed, the governor is at that time operating with the least resist-ance to pressure on the 'rod 21, und et that time also, the spring 18 of the valve 1i' is not pressing against the urm 33.y But when the throttle valve is Wide open or spproximutely so, the motor is usually run ning fast and the pressure is therefore greatest in the governor 15 and the governor is oering its greatest resistance to pressure on the rod 21, the governor of course tending1 to close the throttle valve.

lhe operating: rod 2l is adapted tothe and an adjustable abutment 27, also' on the it will he seen that there is only an arm 2R on. a rock shaft 29 mounted at,

l? so that the. lutter may be opened as the forno of :in aecelerator pedai'll. The springs At this time also the arm 33 is in its most forward position and the valve 17 is wide open, hence the spring 18 is tending to press the arm 33 rearwardly. There is further tendency to close the throttle by reason of the fact that the rearward springQ is somewhat compressed, provided olf course that the hand controlled lever 23 is in the position shown in Figs. 1 and 2 otz the drawings. lt will be obvious that these various'tendencies to move the operating rod 21 rearwardly are communicated to the accelerator pedal 24 through the rock shaft 29 and the link 31, but it. will be seen upon reference to Fig. 2, that the toggle 1necha nism 31--32 is at this time approximately at the point of its greatest leverage, the toggle being very nearly closed, and the same is true also of the toggle connection between the governor and the throttle valve 14. Under the circumstances, it is comparatively an easy matter for the operator to hold down the accelerator pedal 24, but upon his release thereof, the governor operates immediately to close or partially close the throttle and restore the rod and connections to the position in which they are shown in v Fig. 1.

Other forms of the invention than that shown may be used without departing from the spirit or scope of the invention and the specification and claims are intended to cover such modications.

Having thus described my invention, what l claim and' desire to secure by Letters Pat- "ent is 1. ln a hydrocarbon motor, the combination with the intake pipe and the throttle valve therein, of a governor, toggle lever connections' between. the governor and said valve, a second toggle, means by which said second toggle may b e operated, and connec tions between-said second toggle and said valve.v .l

2. ln a hydrocarbon motor, the combination .with the intake pipe and the throttle valve therein, of a governor, toggle lever l connections between. the governor and said valve, a lever adapted to be controlled by the operator, a toggle operated by said lever, and connections between said latter toggle and Said valve.

3. In a hydrocarbon motor, the co1nbination with the intakeI pipe and the throttle valve therein, ot a governor, a toggle between said governor and said valve, and a second toggle adapted to operate the first toggle.

4. In a hydrocarbon motor, the combination with the intake pipe and the throttle valve therein, oflan operating rod 'for said valve, and a toggle mechanism for actuating said operating rod.

5. ln a hydrocarbon motor, the combination with the intake pipe and the throttle valve therein, of a valve for regulating the oil supply of the motor, and a. toggle mechanism for operating both ot' said valves.

6. ln a hydrocarbon motor, the combination with the intake pipeI and the throttle valve therein, of a valve for regulating the oil supply of the motor, a rock shaft, an arm on said rock shaft for operating said oil valve, a toggle mechanism controlled by the operator for rocking said shaft, and connections from said rock shaft to operate .said throttle valve.

7 In a. hydrocarbon motor, the combination with the intake pipe and the throttle valve therein, of a valve for regulating the oil supply of the motor, a toggle connection from the governor to the throttle valve, and a second toggle mechanism controlled by the operator and having connections with both of said valves, both of said toggles reaching approximately their greatest leverage when both valves are open.

In testimony whereof I affix my signature in the presence of two Witnesses.
